Title: Storage of metabolically active material
IPC: A23B4/16
Filed: 1974-05-07
Abstract: 1474602 Storage of organic material GRUMMAN ALLIED INDUSTRIES Inc 7 May 1974 20127/74 Heading A2D [Also in Division F4] A method of creating and maintaining a gaseous atmosphere at a predetermined temperature, sub-atmospheric pressure and high relative humidity in a storage chamber for preserving organic matter comprises bringing ambient air to the required temperature, pressure and relative humidity by causing the ambient air to flow through a restricted opening while reducing the pressure of the air, expanding the air and reducing the relative humidity thereof, causing the expanded air to flow into contact with water to evaporate the water, the expansion of the air and evaporation of the water cooling and humidifying the air, causing the humid air to flow through the chamber and simultaneously removing humid air and gases of respiration of said matter from the chamber, wherein the cooling effect of the expansion and evaporation is modified by changing the temperature of the water when the temperature in the chamber tends to depart from the predetermined temperature. Preferably, air is removed from the chamber at a rate sufficient to remove deleterious gaseous respiration products from the matter being preserved therein so that e.g. there is at least one change per hour of air in the chamber. Suitably the air pressure in the chamber is maintained at or between 4 and 400 mm. Hg absolute, the temperature of the air in the chamber is at or between 32‹F and 48‹F and the relative humidity is near but less than saturation at the corresponding temperature therein. The cooling effect of the expansion and evaporation is preferably modified by changing the rate of flow of air through the chamber. The method may be carried out in the apparatus shown in Fig. 1, wherein air enters the apparatus at inlet 14 and passes via heat exchanger 16 and pressure reduction valve 18 to evaporator 22: The resulting humidified cooled air passes into chamber 16 via nozzle 26, this air impinging upon radiator 32. Air exits the chamber via valve 28. The chamber is provided with a temperature sensor 36 connected to heating element 44. The water in the evaporator may thus be heated in response to the sensor 36 so as to achieve a desired air temperature in chamber 12. In an alternative form of apparatus (Fig. 2, not shown) an oil seal pump is used to produce the vacuum, and the pump oil is used as a heating source for water in the evaporator.

Title: Improvements in aircraft control mechanism
IPC: B64C13/24
Filed: 1946-07-05
Abstract: 614,102. Controlling aircraft. LACHMANN, G. V., and SUPPANCIC, G..O. July 5, 1946, Nos. 20158/46 and 2275/47. [Class 4] In order to impart " feel to a poweroperated aircraft control system, the control operating member is subjected to an elastic reaction, the intensity of which is selectively varied to suit changes in airspeed by means responsive to, or the operation whereof is a function of, the dynamic head. The embodiment shown in Figs. 1, 3 (b) and 4 makes use of an infinitely variable gear mechanism such as is described in Specification 576,536, [Group XXIV], comprising two shafts A20, A21 connected to a layshaft A22 by two universal joints whose yokes A24, A25 are 90 degrees out of phase. The shaft A21 is attached to an arm A211, Fig. 4, connected by a link A40 to a nut A41 mounted on a screw-threaded portion A42 of push-pull connection A43 connected by a lever A44 to the pilot's control member, and the arm A211 carries two compression springs A80, A81 between forked arms A201 attached to the shaft A20. The velocity ratio between the shafts A20, A21 is governed by the inclination of the layshaft A22, increasing as it is moved further out of alignment with the shafts A20, A21. The torsional coupling between the latter forms a light-reaction system which functions alone up to a predetermined airspeed, and the springs A80, A81 a heavyreaction system which is brought into operation as the airspeed increases above the predetermined value. The inclination of the layshaft A22 is controlled by an electric actuator A33, Fig. 3 (b), the operation of which is governed by an air pressure capsule. The increase in inclination of the shaft A22 with speed results in an increase of the velocity ratio between the shafts A20, A21, and hence of the relative movement between the members A201, A211 and of the degree of compression of one or other of the heavy-reaction springs A80, A81. Fig. 5 shows a modification in which the torsion-bar system and the opposed helical springs A80, A81 are replaced by indiarubber or other resilient couplings B70, B80 respectively, which when subjected to torsion as the result of deflection of the lever B201, provide the elastic reaction forces. In the further modification shown in Fig. 6, a shaft C20 which is coupled to the airspeed control system is connected to an output shaft C22 through a Hooke's joint embodying an intermediate elastic member C59 bonded to members C58, C60. Specification 569,290 also is referred to.

Abstract: 998,144. Rotary I.C. engine. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. May 29, 1962 [June 3, 1961], No. 20600/62. Heading F1F. A rotary-piston internal combustion engine comprises a piston 8 mounted on an eccentric 6 fixed to the drive shaft 4, with vanes 9, supported on the shaft 4, passing through bushes 10 in the piston to make contact with the inner surface of the circular section casing. The eccentric rotates n times as fast as the piston, and in the opposite direction, where n is the number of vanes; for each working space between adjacent vanes, therefore, there are n +1 compression strokes during each revolution of the piston. At or near each point of maximum compression, there is fitted either an inlet port and exhaust port A, or an ignition device C. As shown in Fig. 1, the engine has three vanes 9, two ignition devices 13, 14 and two ports 15, 16, each communicating with a rotary valve 17, 18 which connects the port alternately to an inlet and an exhaust. Each working space undergoes two four stroke cycles per piston revolution. In another embodiment (Fig. 4) there are four vanes 9, three inlets and outlets 55, 56, 57, each communicating with a rotary valve, and two ignition devices 13, 14 to provide, for each working space, one fourstroke cycle (57, 13, 55) and one six-stroke cycle (55, 14, 56, 57), the last stage of the six-stroke cycle being used for scavenging. In another embodiment (Fig. 6), there are five vanes, providing either three four-stroke cycles or two six-stroke cycles. In this embodiment, the adjacent inlets and outlets are not combined in one valve, but have their own, separate, rotary valves. The rotary timing valves may be replaced by plates sliding over the inlet and exhaust ports (Fig. 3, not shown). Alternatively, valves may be located on the end walls of the engine, as in Fig. 5, where, on one side a valve member 71 is rotated on a shaft 75 driven through gearing 74 by the drive shaft 4, and on the other side a valve plate 63 is moved by a peg 68 which engages a cam track 67 in the engine flywheel 66.
